To all whom it may concern:

Be it known that I, MAURICE DUESBERG- DELREZ, a subject of the King ofBelgium, residing at Verviers, Province of Liege,Belgium, have inventedan Improvement in Apparatus for Setting Teeth in Card-Clothing,(patented in Belgium December 31, 1890, No. 93,303, and February 28,1891, No. 93,791; in Germany April 10, 1891, No. 60,104; in FranceFebruary 19, 1891, No. 211,5.18; in Italy February 23, 1891, No. 29,259;in England March 5,1891, No. 3,981; in Spain February 25, 1891, No.11,814, and in Austria-Hungary Decemher 5, 1891, No. 36,746 and No.61,729,) of which the following description,in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object the pro? duction of mechanism forsetting teeth in card clothing such as shown in United States Patent No.495,694, granted to me April 18, 1893, the said card clothing beingcomposed of a flexible backing, and teeth inserted therein and havingsupplementary angles at their bases, and inasmuch as the feeding,cutting, and insertion of the Wire into the backing of the clothing maybe and are performed by any usual or suitable mechanism, forming no partof this invention, I have not illustrated the same herein. In accordancetherewith my invention consists in a machine for setting card teeth, ofa matrix, and means to sustain the backing adjacent thereto with thecard teeth projecting over said matrix, combined with a bender, andmeans to move it toward the matrix to deliver a blow upon the projecting teeth,whereby the latter are forced against the matrix and bent to theshape thereof, substantially as will be described.

Other feat ures of my invention will be hereinafter described andparticularly pointed out in the claims.

Figure 1, is a top view partly in section, of a sufficient portion of acard tooth setting machine to be understood, and embodying my invention.Fig. 2 is an end view of the mechanism shown in Fig. 1, partly insection. Figs. 3 and 4 are enlarged details in plan and side elevation,respectively, of the mechanism shown in Figs. 1 and 2. Fig. 5 isamodification of the matrix and bender to be described, and Fig. 6 anenlarged section of the matrix.

Referring to the drawings, I have shown the leather orother materialforming the backing A of the card clothing as suspended over suitableguides a and passed between rolls a, a, see Fig. 2, preferablycorrugated to more readily grasp and control the movements of thebacking. The said backing is moved upward by any suitable means, such asa weight upon its leading end, the rolls a, a regulating the rapidity ofthe longitudinal movement of the backing, and being rotatedintermittingly in the usual manner. The backing is pressed by a guideroll a against the vertical face of a matrixB, its upper surface havinga longitudinal groove or depression b therein, see Figs. 1, 2, 4t and 6,formed by the intersection of the two sides 1), b for a purpose to bedescribed, the matrix being attached to a bridge 0 secured to bracketsc, c forming a part of the machine frame.

Lateral motion is imparted to the backing A step by step as each toothis brought into position to be set, by mechanism of usual and well knownconstruction, in order that the teeth in each horizontal row may be setsuccessively, the backing being moved longitudinally at the completionof each row to present a new row of teeth to be acted upon by thesetting mechanism. In setting the teeth each one is bent to formsupplemental angles at the base, as described in the patent referred to,so as to present a broken or crooked line.

In forming ordinary card-teeth a hooked tool has been employed to pullthe teeth in a downward direction over a suitable tongue and therebybend it, butin forming the teeth in accordance with my invention, Iexert sudden pressure upon the tooth by a blow, delivered by a bender orformer, now to be described.

A rock shaft 61 is supported in suitable bearings d in brackets dforminga part of the frame of the machine, to which shaft is secured anarm cl supporting a carrier 6 grooved or recessed at its upper side, seeFigs. 3 and 4, to receive and guide the benders or formers e upturned attheir inner ends to form ears e through which screws e are extended, bymeans of which the benders or formers can be adjusted longitudinally andindependently. Set screws f are extended through slots f in the bendersinto the carrier, whereby the benders can be rigidly secured in adjustedposition, and the front ends thereof can be raised or lowered byadjusting screws f Each bender e acts upon one of the two legs orbranches of a tooth, and by means of the independent adjustment the twolegs may be. given a slightly different form, and wear of the parts isprovided for. As shown in Fig. 4 the arm (1 is adjustable upon the rockshaft d by a set screw d In order that the bender, having formed or setthe teeth of one row, may not contact therewith improperly when formingthe teeth of the next row, I oscillate the bender, and for that purposeI have shown herein a gear (1 fast on the rock shaft d, in mesh with areciprocating rack bar (i motion being imparted thereto by a cam orotherwise, whereby the carrier is moved in a circular path toward andfrom the matrix B as the shaft is rocked. As will be seen by aninspection of Figs. 2 and 4 the front end of the benders e are curved,the extremities e being slightly rounded. The legs of the tooth havingbeen forced into and through the backing A, they are brought intoposition against the edge 11 of the matrix, and projecting over it,whereupon the carrier e is oscillated as described and the extremitiesof the benders strike against the top of the wire, forcing the legs downinto the groove 1) of the matrix and against the sides b, 1) thereof,bending the legs in opposite directions and forming the supplementalangles desired, at the same time directing the points upward. Owing tothe convexity of the tops of the benders the points of the teeth immediately above and in the preceding row are bent upward slightly, togive them the proper final inclination, while the concave under side ofthe bender permits free movement of the point of the tooth receiving theblow, as the point will rise when the adjacent part is forced by theblow into the groove b of the matrix. The point is thus protected andcannot be bent during the impact, and when the bender is withdrawn itwill not touch the point.

It is obvious that the bends or angles may be altered in number oramplitude by changing the form of the matrix and the end of thebender,as in Fig. 5, wherein two bends in each direction are imparted to thebase of the tooth by the matrix B and bender e' This invention is notrestricted to the precise form or arrangement of parts as herein shownand described, as it is evident that they may be altered or modifiedwithout departing from the spirit and scope of my invention.

I claim 1. In a machine for setting card teeth, a matrix, and means tosustain the backing adjacent thereto with the card teeth projecting oversaid matrix, combined with a bender, and means to move it toward thematrix to deliver a blow upon the projecting teeth, whereby the latterare forced against the matrix and bent to the shape thereof,substantially as described.

2. In a machine for setting card teeth, a matrix having a groove ordepression therein, and means to sustain the backing adjacent theretowith the card teeth projecting over the matrix, combined with anoscillating bender, and means to move it against the teeth and forcethem into the groove of the matrix, to bend the teeth at their base,substantially as described. I

3. In a machine for setting card teeth, a matrix having an edge 12 agroove with inclined walls, and means to sustain the backing with theteeth to be set extended over said edge and groove, combined with abender adapted to deliver a blow upon the teeth and bend them over theedge and into the groove, to

form supplemental angles at the base, actuating means for said bender,and adjusting devices to vary the throw of the bender, substantially asdescribed.

4. In a machine for setting card teeth, a ma trix to impart the desiredshape to the teeth, combined with a bender adapted to force the teethagainst said matrix and thereby shape them, the under side of the benderbeing concave, substantially as and for the purpose described.

5. In a machine for setting card teeth, a matrix to impart the desiredshape to the teeth, combined with abender adapted to force the teethagainst the matrix, the top of said bender being convex, to act upon thepoint of a tooth in the preceding row and adjust its inclination,substantially as described.

' 6. In a machine for setting card teeth, a matrix to impart the desiredshape to the teeth, combined with a bender adapted to force the teethagainst the matrix, the top of said bender being convex, to act upon thepoint of a tooth in the preceding row and adjust its inclination, thebender being curved atits under side to permit free movement of thepoint of the tooth being set, substantially as described.

7. In a machine for setting card teeth, a rock shaft, a carrier thereon,and independent benders supported by said carrier, combined with meansto adjust said benders independently, and a matrix to co-operate withthe benders, substantially as described.

In testimony whereof- I have signed my name to this specification in thepresence of two subscribing witnesses.
